IsoKenetic Stack Train IST Sampler
IST Method 5 sampler systems are manufactured to conform with the construction design criteria and specifications cited in US EPA Method 5, Code of Federal Regulations (40CFR Part 60) and APTD-0581 Document. Our source sampler consoles allow operators to monitor gas velocities, temperatures, pressures and sample flow rates in order to maintain isokinetic sampling conditions. For sampling to be isokinetic the sample gas enters the nozzle at a velocity equal to the approaching gas velocity. All Apex Instruments models are interchangeable and compatible with most others currently in use. Our 572 Series Consoles are equipped with Metric instruments and ultra high molecular weight (UHMW) polyethylene case.
The professional source sampling company must be prepared for a wide variety of conditions and locations. Apex recommends the “Deluxe Plus” system, which can be used in both rigid and flexible configurations. Even with the classic rigid arrangement, the additional glassware allows you to have pre-measured and filled impingers, pre-weighed filter assemblies, and minimum turnaround time between runs. The flexible arrangement is effective for challenging environments like vertical traverses and space-limited sources.

The Method 29 determination of metal emissions from hazardous waste incinerators involves a modification of the Method 5 train. The sampling train is the same as a Method 5 particulate train with the addition of up to three impingers to enhance the collection of metals of interest. The impinger train requires the SB-4 impinger case, glass nozzles, probe liners and non-metallic union. The method has been validated for the collection of 17 different metals.

NO/NO2/NOX Analyzer uses Chemiluminescence which is the best practical analytical method for NOx detection. When an NO (nitric oxide) molecule reacts with ozone, it is oxidized to NO2, in an excited state. A small fraction of the molecules in this excited state decays by emitting a photon (i.e. giving off light) in the near infrared portion of the spectrum. The concentration of NOx in the sample is determined by the amount of light emitted from the mixed gas sample. This technique provides an extraordinarily sensitive, selective, and linear measurement of NOx. |

CO Analyzer measures carbon monoxide by passing infrared light through sample and determining the absorbed energy and then compare this to that absorbed by a reference gas. This is accomplished with a Gas Filter wheel which alternately allows a high energy light source to pass through a CO filled chamber and a chamber with no CO present.

The Ozone Analyzer is a microprocessor-controlled analyzer for measuring low ranges of ozone in ambient air. An Ultraviolet light is passed through a sample cell. The light is absorbed, depending on the amount of ozone present. The true value of the ozone is proportional to the absorption. |

Chemiluminescent NH3 Analyzer measures ambient ammonia in selectable ranges from 0-50 ppb to 0-2,000 ppb using the chemiluminescence principle and an API designed external ammonia converter and sampling system Ranges are user selectable in 1 ppb increments and auto ranging is available. Ammonia is difficult to measure accurately because of a tendency to be absorbed into other materials. |

TRS provide a dependable, accurate and convenient method of measuring hydrogen sulfide or Total Reduced Sulfur (TRS) in levels commonly required for Ambient Air monitoring, offering ranges from 0-50 ppb to 0-10 ppm. Both analyzers convert sulfur gases to sulfur dioxide and measure concentrations using fluorescence technology. |

The H2S analyzer provides a dependable, accurate and convenient method of measuring hydrogen sulfide in levels commonly required for Ambient Air monitoring, offering ranges from 0-50 ppb to 0-10 ppm. The analyzers convert sulfur gases to sulfur dioxide and measure concentrations using fluorescence technology.
